The Institute of Mixture Modeling for Equity-Oriented Researchers, Scholars, and Educators (IMMERSE) is an IES funded training grant (R305B220021) to support education scholars in integrating mixture modeling into their research.

To demonstrate mixture modeling in the training program and online resource components of the IES grant we utilize the Civil Rights Data Collection (CRDC) (CRDC) data repository. The CRDC is a federally mandated school-level data collection effort that occurs every other year. This public data is currently available for selected latent class indicators across 4 years (2011, 2013, 2015, 2017) and all US states. In this example, we use the Arizona state sample. We utilize six focal indicators which constitute the latent class model in our example; three variables which report on harassment/bullying in schools based on disability, race, or sex, and three variables on full-time equivalent school staff hires (counselor, psychologist, law enforcement). This data source also includes covariates on a variety of subjects and distal outcomes reported in 2018 such as math/reading assessments and graduation rates.

Variables have been transformed to be dichotomous indicators using the following coding strategy
Harassment and bullying count variables are recoded 1 if
the school reported at least one incident of harassment (0
indicates no reported incidents). On the original scale reported by the
CDRC staff variables for full time equivalent employees (FTE) are
represented as 1 and part time employees are represented by
values between 1 and 0. Schools with greater
than one staff of the designated type are represented by values greater
than 1. All values greater than zero were recorded as 1s
(e.g., .5, 1,3) indicating that
the school has a staff present on campus at least part time. Schools
with no staff of the designated type are indicated as 0 for
the dichotomous variable.

MplusAutomationWHAT?
MplusAutomation is an R packageMplus programR & Mplus softwareWHY?
MplusAutomation can provide clearly organized work
procedures in which every research decision can be documented in a
single placeHOW?
Below is a template for mplusObject() &
mplusModeler() functions. Use this template to run
statistical models with Mplus.
m_template <- mplusObject(
TITLE =
"",
VARIABLE =
"",
ANALYSIS =
"",
PLOT =
"",
OUTPUT =
"",
usevariables = colnames(),
rdata = )
m_template_fit <- mplusModeler(m_template,
dataout=here("", ".dat"),
modelout=here("", ".inp"),
check=TRUE, run = TRUE, hashfilename = FALSE)
This code uses the mplusObject function in the
MplusAutomation package and saves all model runs in the
enum folder.
lca_6 <- lapply(1:6, function(k) {
lca_enum <- mplusObject(
TITLE = glue("{k}-Class"),
VARIABLE = glue(
"categorical = report_dis-law_fte;
usevar = report_dis-law_fte;
classes = c({k}); "),
ANALYSIS =
"estimator = mlr;
type = mixture;
starts = 200 100;
processors = 10;",
OUTPUT = "sampstat residual tech11 tech14;",
PLOT =
"type = plot3;
series = report_dis-law_fte(*);",
usevariables = colnames(df_bully),
rdata = df_bully)
lca_enum_fit <- mplusModeler(lca_enum,
dataout=glue(here("enum", "bully.dat")),
modelout=glue(here("enum", "c{k}_bully.inp")) ,
check=TRUE, run = TRUE, hashfilename = FALSE)
})
IMPORTANT: Before moving forward, make sure to open each output document to ensure models were estimated normally.
First, extract data:
#
output_bully <- readModels(here("enum"), filefilter = "bully", quiet = TRUE)
enum_extract <- LatexSummaryTable(
output_bully,
keepCols = c(
"Title",
"Parameters",
"LL",
"BIC",
"aBIC",
"BLRT_PValue",
"T11_VLMR_PValue",
"Observations"
),
sortBy = "Title"
)
allFit <- enum_extract %>%
mutate(CAIC = -2 * LL + Parameters * (log(Observations) + 1)) %>%
mutate(AWE = -2 * LL + 2 * Parameters * (log(Observations) + 1.5)) %>%
mutate(SIC = -.5 * BIC) %>%
mutate(expSIC = exp(SIC - max(SIC))) %>%
mutate(BF = exp(SIC - lead(SIC))) %>%
mutate(cmPk = expSIC / sum(expSIC)) %>%
dplyr::select(1:5, 9:10, 6:7, 13, 14) %>%
arrange(Parameters)
Then, create table:
fit_table1 <- allFit %>%
gt() %>%
tab_header(title = md("**Model Fit Summary Table**")) %>%
cols_label(
Title = "Classes",

LL = md("*LL*"),
